18 / 243 page  Obsolete Product(s) - Obsolete Product(s) Description ST72325xxx-Auto 18/243 Doc ID 13770 Rev 3 1 Description The ST72325-Auto devices are members of the ST7 microcontroller family designed for mid-range automotive applications running from 3.8 to 5.5V. Different package options offer up to 48 I/O pins. They are derivatives of the ST72321 and ST72324 devices, with enhanced characteristics and robust Clock Security System. All devices are based on a common industry-standard 8-bit core, featuring an enhanced instruction set and are available with Flash program memory. The ST7 family architecture offers both power and flexibility to software developers, enabling the design of highly efficient and compact application code. The on-chip peripherals include an A/D converter, a PWM autoreload timer, two general purpose timers, I2C, SPI and SCI interfaces. For power economy, the microcontroller can switch dynamically into Wait, Slow, Active Halt or Halt mode when the application is in idle or standby state. Typical applications include ● all types of car body applications such as window lift, DC motor control, rain sensors ● safety microcontroller in airbag and engine management applications ● auxiliary functions in car radios The devices feature an on-chip Debug Module (DM) to support in-circuit debugging (ICD). For a description of the DM registers, refer to the ST7 ICC Protocol Reference Manual. Main differences with ST72321: ● LQFP32 package ● Clock Security System ● Internal RC, readout protection, LVD and PLL without limitations ● Negative current injection not allowed on I/O port PB0 (instead of PC6) ● External interrupts have Exit from Active Halt mode capability Table 2.
